About this task

The impact tree shows the result of impact rules on CI parent and child
relationships. The tree represents a business service map with CIs from the Service
Configuration Item Association [svc_ci_assoc] table. When related CIs are connected
but not part of the business service map, the impact for the related CIs can also
appear in the impact tree.

The numbers or percentages on a parent CI
summarize overall severity based on alerts from child CIs. The parent severity is
based on impact rule computations.

You can also learn about the impact tree
from the following video tutorial.
